To all whom it may concern: Y

Be it known that I, WILLIAM I-I. PRINZ, a citizen of the United States, residingk at Oak Park, in the county of Cook and State of Illinois, have invented vcertain new anduseful Improvements in Malt-Houses, of which the following is a specification, reference being had to the accompanying drawings.

My invention relates to the treatment of grain for the production of malt, and has particularly to do with apparatus oflthe type illustrated and'described in my application filed June 11th, 1906, in which provision is made for keeping green malt in aperfectly fresh condition andfor removing from the, mass any desired amount of malt without yinterrupting the Ventilating operation. As explained in the specilication of my said application, the greenmalt is kept` fresh, and further growth prevented, by Ventilating it by the use of air the'moisture of which is less than that required for furl-` ther growth,-this being accomplished" by the use of what I have termed a withering kiln, in which the malt is placed after germination has been carried to the proper point.

to time the perforated lloor ofthe compartment in which the malt is placed is made in removable sections, and an adjustableparti tion or head is provided which closes the end vanced as each sectionor series of sections of the {ioor is removed so as' to constantly close the end of said channel,- and thus ventilation may continue without substantial interruption. These featuresare` also included, generically'speaking, in the apparatus of my present application, whichA differsl from the subject-matter of my, pending application principally in two respects., The first has to do with the course'of the air in Ventilating the malt in the witheringki-ln. a In the apparatus of my pendingtapplication the air passes downward through the Vmalt vvand thence out to the exhaust chamber. 4In the construction ofm'ylpresent application the :How ,of airfis reversed, -theair passing upward through` the malt and thence out. I also provide means bywhich the withering kiln may be supplied either with external or In order to permit ,of the' removal ofV instalments of malt from the. kiln from time' attemperator room alone, or with a mixture of air from both sources.

The other novel feature of my present application consists in the arrangement and devices provided for closing the end of the channelV under the floor of the compartment in the withering kiln. In my pending apJ plication said channel is closed by a hinged or folding partition which extends entirely across thespaoe beneath the compartment floor. In the apparatus of my present application I employ a comparatively short partition, which is preferably rigid from 'end to end and which doesl not extend beneath the marginal stationary sections ofthe compartment floor, so that it is more easily handled. Moreover, I provide short stationary'transverse supports or partition extensions beneath the stationary lateral sections of the compartment floor which provide a substantial 'support and cooperate with the partition to close the end of the air channel as the partition is advanced from pointrto point.

In other respects the construction shown v in my present application is substantially the same as in my Apending application, since I employ one or more-preferably two -malt ing floors containing the usual gernnnating compartments, which are ventilated in the same manner as In my pending application, receiving air from the vattemperator room which also Supplies air to the withering kiln. Similar conveyer mechanism is also provided 'f' for 'delivering the malt from the compartment rooms to the withering kiln.

, In the accompanying drawings,-Figure 1 is alongitudinal vertical section of the building illustrating my invention; Fig. 2

is a vertical cross-section thereof, looking to,

theleft; Fig. 3 is an 'enlarged detail, partly in section, illustrating the construction. of the malting compartment in the withering kiln; Fig. 4 is a partial horizontal section Von line 4 4 of Fig. 3; Fig. 5 is a detail of the floor of the withering kiln; Fig. 6 is an enlarged sectional detail taken on line 6-6 of Fig..1; .and'Fig. 7 is a view illustrating the floor plan of the withering kiln compartment with adjacent parts-.

Referring to the drawings,-8-9 indicate the end walls, and 10-11 the side walls of the building', which may be of any suitable shape.

12-18 indicate the compartment floors, 14 the attemperator floor, and 15 the withering kiln,-which are preferably arranged in the order shown, the withering kiln being at the top of the building. Obviously, any number of malting floors may be provided, and any number of malting compartments may be provided. 1n the construction illustrated have shown each malting floor as having two malting compartments 16-17 between which is a gangway 1S and a iioor 19.

As shown in Fig. 6, the Hoor 19 of the upper gangway 18 is perforated in part as is also the floor 20 beneath said floor 19 so that air may pass through the perforated portions of said floors 19-2O to the lower compartment-room. Thus air from the upper compartment room is supplied to the lower room. A part only of the floors 19-20 is perforated as sutlicient capacity can bejsecured without perforating the entire iioor.

21 indicates the perforated tioors of the various malting compartments.

22 indicates vertical iiues, into which air passing through the perforated ioors of the malting compartment is discharged through air channels 28 under the compartment fioors. Valves Q41 are provided for regulating the area of the outlet passages. The flues 22 discharge into an exhaust chamber 25 provided with a fan 26 by which the flow of air is maintained.

27 indicates malt turners for agitating the grain in the malting compartijnents. Said turners are of the usual well-known type.

' 28-29 indicate gangways adjacent to the wall 8, which extend transversely of the malting compartment rooms, as shown in Fig. i,

3() indicates a passage in the floor of the gangway 2S through' which the malt from the lower compartments may be delivered to a transverse conveyer 31. Similarly, 32 indicates a passageway in the floor of the upper gangway 29 through which the malt from the upper compartment room may be delivered to the gangway 2S and thence to the conveyor 31. The openings 30-32 are normally closed by covers B25-34, respectively. As indicated in Fig. 2, the conveyer 31 communicates with an elevator 35 which elevates the malt and discharges it into a longitudinally-extending conveyer 36, shown in Fig. 2, which in turn delivers it to transverse conveyers 37 which extend into the withering kiln 15, as shown in Figs. 2 and 7.

Said conveyers 37 are provided with adjustable spouts 38, as shown in Fig. 2, by which the malt may be properly distributed. The elevator 35 and conveyers 3637 are driven vpreferably by means of a shaft 39 and a sprocket wheel 40, power being supplied from any source, but they may be driven in any other suitable way.

As best shown in Fig. 1, the attemperator room '14 is provided with one or more passages 11 through which air may pass into the upper compartment room 13. Air is admitted to the attemperator room through valved openings 12, or in any other suitable way. 13 indicates heaters which are preferably provided opposite the opening 4Q so that when necessary the incoming air may be properly heated. @la indicates attemperators of the usual type, in which the air is properly moistened or cooled, or both. 15 indicates a passageway controlled by a valve 46 through which air is admitted from the attemperator room 1a to a mixing chamber 17 communicating` with the withering kiln 15. '-18 indicates an opening adapted to admit external or atmospheric air to the mixing chamber 17. 49 indicates heaters for heating air entering through the opening 4S. 50 indicates a valve for controlling the admission of air from the opening 48 to the mixing chamber -l-7. As best shown in Fig. 1, the mixing chamber 17 communicates with an air channel 51 beneath the perforated tloor 52 of the malt compartment 53 of the withering kiln, so that air from the atteinpe'rator room, atmospheric air, or both, may

be admitted to the channel 51 and thence may rise through the malt into the kiln couipartment. 5st indicates a passageway, having a valve 5am, through which air from the kiln compartment may pass to an exhaust room 55 provided with a fan 5G for discharging the foul air received from the kiln.

The construction of the kiln compartment is best shown in Figs. 2, 3 and el.. As shown in Figs. 1 and 2, the tloor of the kiln compartment is made up of two stationary marginal sections 57--5S, respectively, which are perforated to permit of the passage of air through them. Between said marginal floor sections are removable intermediate sections 59-60-61. The removable portion of the floor of the kiln compartment is made up of a plurality of removable sections, or series of sections, the arrangement being such that by removing a section or transverse series of sections the length of the floor may be rcduced from time to time to oiiset the removal of a corresponding quantity of malt. I prefer to arrange the sections in transverse series of three, but this is not essential. G2 indicates a series of stationary transverse partitions placed so as to aline with the edges of the intermediate tloor sections 59 G0-G1 and support the same. G3 indicates a movable partition which is adapted to aline with the opposite stationary partitions G2 against the edges of which its ends abut, as shown in Fig. t. The movable partition 63 is provided with rollers 64 ou which it runs. The arrangement is such that as each soirees Successive series of removable Hoor sections is removed the removable partition 63 may be advanced to the next pair of stationary partitions, and as such movablepartition cooperates with the stationary partitions to entirely close thev channel under the compartment Hoor it is apparent that ventilation of the malt in the kiln compartment may be continued substantially without interruption, notwithstanding the removal of the instalments of malt.

able construction.

From the foregoing description itwill be seen that ventilation of the malt in the kiln' compartment is secured by causing 'air `to pass upward through the malt, and that such air may be taken directly 'from the attemperator room, from outside of the building, or may be a mixture-of air from both sources; also that the ventilation of the malt may he continued without substantialinterruption notwithstanding the removal from time to time of portions thereof. In

practice a cart is runjinto the compartment` between the stationary floor sections and the malt shoveled' into it.
